extremum method meaning in Chinese

极值法

Several complementary computing dimension chain formulas of extremum method and probability method are deduced
推导了使用极值法、概率法计算尺寸链的补充公式。
The matching rate of the suggested two methods were compared for the assembly size chaims with different number of the forming links , with different number of the forming link parts , and with different deviation distribution types on the assumption that the closing link tolerance of the selective assembly is a tenth of that calcalated by the extremum method
以不同组成环数、不同组成环零件数、不同偏差分布类型的装配尺寸链为研究对象，取选择装配的封闭环公差为按极值法计算所得封闭环公差的十分之一，以匹配率为评价指标，比较了两种方法的优劣。
